Abstract
Vegetables are essential for human health. All vegetables are source of all kinds of essential minerals and trace elements. Presence of some selected heavy metals such as Cr, Cd, Zn, Cu and Pb in different vegetable samples were investigated, which were collected from various locations (Genda Bazar, Sadapur and Savar thana bazar) of Savar at Dhaka, Bangladesh from December 2019 to May 2020. Samples were digested by acid digestion and heavy metals were determined by Analtik JenaovAA 400P Atomic Absorption Spectrophotometer. Total 24 samples were collected from these places. Heavy metal concentrations in the samples were found to be in the range of 1.0-2.14 mg/kg of Cr, 0.03-0.49 mg/kg of Cd, 0.01-2.99 mg/kg of Pb, 0.40-1.30 mg/kg of Cu and 0.14-4.40 mg/kg of Zn. In all samples, Pb was found in high concentrations and Cd was found high only in bottle gourd. The World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) suggested the maximum permissible values of Cr (2.3mg/kg), Cd (0.2 mg/kg), Pb (0.3 mg/kg), Zn (99.4 mg/kg) and Ni (67.9 mg/kg) in vegetables. Although not all heavy metals exceed WHO/FAO's specified value, the amount obtained is a significant threat to us.
Key Words: Vegetable, Heavy metal, Savar and Bangladesh.
